Pruritic urticarial papules and plaques of pregnancy in twin and triplet pregnancies.

Author information

Regional Centre of Dermatology, Mater Hospital, Dublin, Ireland.



Pruritic urticarial papules and plaques of pregnancy (PUPPP) is a common dermatosis of unknown aetiology. Multiple pregnancies occur frequently in most reported series of PUPPP and increased abdominal distension has been considered a factor in its causation.


To determine the frequency of PUPPP in twin and triplet pregnancies.


A retrospective review of all the records of patients delivered of twin or triplet pregnancies over an 18-month period at a busy general maternity hospital.


One hundred and thirty-eight women delivered twins, four of whom developed PUPPP (2.9%). Fourteen women delivered triplet pregnancies, two of whom developed PUPPP (14%). Four of these six multiple pregnancies were conceived by in vitro fertilization.


The reported rate of PUPPP in single pregnancies is 1 in 200 (0.5%). Our findings suggest that multiple pregnancies are at a higher risk of developing this cutaneous eruption with 2.9% of twin and 14% of triplet pregnancies affected in our study.
